8: The Network Adapter Manager
•Windows 95, 98, NT and Me
•Windows 2000 and XP
•
•Closing the Network Adapter Manager
Note: The Network Adapter Manager launches automatically whenever Windows is started. Unless you manually exit the application, it remains running from the time you start Windows until you shut down. Generally, the status area icon is the only evidence that the Network Adapter Manager is running.
Note: The tooltip, displayed when you position the pointer over the Network Adapter Manager icon in the status area, identifies the primary card.
The AirCard 555 wireless network card comes with an appli- cation, called the Network Adapter Manager, that is designed to manage multiple network interface cards.
To understand the purpose of the Network Adapter Manager, it is necessary to understand that the AirCard behaves differ- ently for each type of connection. The AirCard 555 behaves as:
•A modem during
•A phone during voice connections
•A network interface card during Express Network (1xRTT) connections
It is only while the AirCard 555 is behaving as a network interface card (when there is an active 1xRTT connection) that the Network Adapter Manager is of use.
When you have more than one network interface card inserted, Windows routes the data traffic through only one of the cards. This means that when you have a 1xRTT connection with the AirCard 555, and you have another network interface card (such as an Ethernet or Token Ring LAN card) inserted, data traffic is routed through either the AirCard 555 or the LAN card — not both. The card through which data traffic is being routed is the “primary” card. The Network Adapter Manager shows you which card is primary by displaying an icon in the status area (usually located in the lower right corner of your screen).
Depending on which card is primary, the Network Adapter Manager displays one of these icons.
AirCard 300 is the primary network card
AirCard 400 is the primary network card
AirCard 555 is the primary network card
LAN card is the primary network card
No network card is inserted (This icon is always displayed in Windows 2000, except during 1xRTT connections.)
